Anesthesia and transport of fat snook Centropomus parallelus with the essential oil of Nectandra megapotamica(Spreng.) Mez [PDF]
This study analyzed the chemical composition and anesthetic potential of essential oil (EO) of Nectandra megapotamica in fat snook (Centropomus parallelus). For the extraction of EO by hydrodistillation, leaves were separated in young (EO-Y) or old (EO-O), and the chemical composition of the EOs was determined by CG-MS.

Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs
ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the

Anesthetic induction and recovery time of Centropomus parallelus exposed to the essential oil of Aloysia triphylla [PDF]
ABSTRACT: This study analyzed the effectiveness of the essential oil of Aloysia triphylla (EOA) as an anesthetic and stress reducing agent in the transport of fat snook ( Centropomus parallelus ). Juveniles were exposed to different concentrations of EOA (seawater-adapted: 25-300μL L-1; freshwater-adapted: 200μL L-1) to identify the anesthetic ...

This study evaluated the growth of fat snook Centropomus parallelus in response to the dietary total lipids, gross energy (GE) and crude protein (CP) content. In the 1st experiment, five isonitrogenous diets with 541.7 ± 2.4 g kg-1 CP varied their lipid content in 113, 151, 160, 189 and 200 g kg-1 and GE in 18.8, 19.4, 20.4, 21.2 and 22.2 MJ kg-1 ...

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork
ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay
ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.

Hyperostosis in Fishes: An Update With New Species Records
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

We studied the recovery of juvenile fat snook (Centropomus parallelus) after subchronic exposure to different concentrations of copper. Healthy juveniles (1.98 g) were exposed to 25 or 50 μg Cu/L for 30 days (12 replicates with 5 fish in each one), and recovery was observed at 0, 4, 10, and 30 days after exposure (3 replicates with 5 fish in each one).

Evaluation of catch-and-release angling practices for the fat snook Centropomus parallelus in a Brazilian estuary [PDF]
Recreational fisheries are developing for many iconic marine and estuarine fish species and are gener- ating important social and economic returns in Brazil. Fat snook is the primary target species in southeastern Brazil and it supports a vibrant fisheries sector, including recreational fishing tournaments.
